Hawthorn is an herbal remedy that is used to treat diseases of the blood vessels and heart, including atherosclerosis, irregular heartbeat, chest pain, congestive heart failure and both low and high blood pressure. According to early research, this herb seems to lower blood pressure by relaxing blood vessels far from the heart. However, it can take a few months to have a curative effect.
To prepare a cup of hawthorn tea, pour 1 cup of boiling water over 1 teaspoon of dried hawthorn leaves and/or flowers, cover and steep for 10 minutes. Drink one cup in the morning and one cup in the evening. Hawthorn is generally safe if taken at recommended doses for short periods of time (up to 16 weeks). It is unknown if long term use is safe. Reported side effects include stomach upset, nausea, fatigue, headache, dizziness, sweating, palpitations and insomnia. If you have a heart condition or are taking medications to treat heart disease, consult with a health care provider before taking.
